Dormer 8030401 | 20.00mm Diameter x 20.00mm Shank x 67.00mm Maximum Depth of Cut x 125.00mm OAL x 0.30mm Radius 5 Flute AlCrN Coated HM S773HB Trochoidal End Mill

With an aluminium chromium nitride coating to reduce friction and provide excellent wear resistance for increased tool life, S773 milling cutters have a 5-flute design which reduces vibration at higher speeds. The FS Style chip dividers break the swarf into manageable pieces to reduce spindle load and increase metal removal, whilst the through coolant further improves swarf removal and is an aid to machining difficulty to machine materials. For an improved surface finish and to further extend tool life by reducing chatter and vibrations, S773HB 5-flute milling cutters have an unequal helix.
